Problems solved by technology

In order to make the vibration effect of the product better, thereby improving the sound effect, the sounder uses a relatively large-quality diaphragm and magnetic steel, or uses two identical sounders, but the large-quality diaphragm will cause the sounder to vibrate Sex and reliability issues; using two identical generators requires a relatively large space, but ultra-thin systems often do not have enough space, and the cost is also high

Abstract

The invention provides a sounder which comprises a vibration system, a magnetic circuit system and a housing accommodating the vibration system and the magnetic circuit system, wherein, the magnetic circuit system comprises a magnetic frame having accommodation space and fixed on the housing and a permanent magnet assembly accommodated in the accommodation space, a magnetic gap is provided between the magnetic frame and the permanent magnet assembly, the vibration system comprises a first diaphragm and a second diaphragm which are attached to the housing and separate from each other to form a certain distance, a voice coil framework with one end connected with the first diaphragm and the other end connected with the second diaphragm, and a first voice coil and a second voice coil wound on the voice coil framework, the voice coil framework is located in the magnetic gap, and the magnetic circuit system is located between the first diaphragm and the second diaphragm. The sounder provided in the invention enables voice effects of a product to be enhanced.

Description

technical field [0001] The invention relates to a sound generator, in particular to an ultra-thin sound generator. Background technique [0002] In order to adapt to the miniaturization and multi-functional development of various audio equipment and information communication equipment, the corresponding needs of the sound generator used in this type of equipment tend to be more miniaturized, and the cooperation with other components around the sound generator is more compact, Especially with the development of thinner and lighter mobile phones, the sound generator used in it requires not only miniaturization, but also high sound quality and stereo sound. [0003] The sound generator related to the present invention includes a vibrating system provided with a vibrating membrane, a magnetic circuit system provided with a magnet, and a casing for accommodating the vibrating system and the magnetic circuit system. In order to make the vibration effect of the product better, the...
